MACHINE FOR MAKING CORRUGATED PAPER AND PACKING-BOARD.

Specification of Letters Patent.

Patented Apr. as, rare.

Application filed October 20, 1915. Serial No. 56,975.

taining corrugating-rolls, pasting devices,

presser-rolls and drier devices used in the manufacture of corrugated paper having a backing or lining and adapted to the packing of goods for shipping or the like.

The main object of the invention is to provide in a single machine or within the bounds of a single casing or supportingframe a set of devices that is adapted to be operated either single or double, or, in other words, a set that will produce either a single roll or winding of corrugated and lined paper, at one time, or a pair of rolls or windings of corrugated and lined paper one at each end of the machine simultaneously.

Another object is to produce a sheet of double thickness that is suitably stuck together before entering the corrugating-rolls.

Still another object is to produce a corrugated sheet of single or double thickness of material, on a single or on a double lining or backing, the latter form giving added strength.

The machine herein is preferably intended for use in working double, without increasing the amount of space it occupies over that of machines of a similar type that work but a single roll of single-ply paper to be corrugated, or materially increasing the power and attention needed to op erate it.

All the features of the invention will be fully hereinafter described and particularly pointed out in the claims that follow.

In the accompanying several sheets of drawings, Figure 1 is a longitudinal sideelevation showing the entire machine as-it appears in its preferred double-operating use; Fig. 2, aminiature, longitudinal sideelevation introduced merely to show the arrangement of the train of gear along that face of the machine seen in Fig. 1, but omitted from the latter view for the purpose of better disclosing the structure and arrangement of the corrugating, pressing and final drier-rolls and their adjusting devices that would be otherwise concealed; F g. 3, a longitudinal sectional-elevation; F1g. 4, an end-view on a small scale; and

Fig. 5, a transverse section of one of the corrugating-rolls and its bearings, including its heat-introducing tube and condensa-' tion drain-tube.

1 indicates one longitudinal side framemember and 2 a corresponding opposite side frame-member suitably spaced apart and coupled so as to form a supporting-frame for the mechanism of the machine herein. It has been deemed best not to encumber the drawings herein with said spacing and coupling cross or transverse members that would otherwise obscure the view to the several essential elements forming the features of the invention herein.

3 indicates a centrally-disposed master or transmitter rolltransversely mounted between and journaled in the longitudinal side-members l and 2, its periphery being suitably corrugated to serve as a shaperr0 fl indicates a corrugated roll horizontally alined with roll 3 and adapted to mesh therewith, and 5 is another corrugated roll, corresponding to and in horizontal alinement with the said rolls 8 and 4, and with its corrugations meshing with those of the master shaper-roll 8 but diametrically opposite to the meshing point of roll at with roll 3, as best shown in Fig. 3.

Rolls 3, 4 and 5 thus form a train of corrugators, the middle one 3 being practically the corrugator or active shaper-roll while the rolls at and 5 form toothed-surfaces' into which the webs of paper are pressed by the teeth of roll 3 in forming corrugations in said webs of paper. These three corrugated rolls are thus arranged so that apair of webs of paper of one or more along the outer face of the side frame-memher 1. A downwardly-turned drain-tube 8 is extended through each axis of the said,

driving power-is transmittedto them'.

corrugating-rolls, as best shown in Fig. 5, whereby the water of condensation maybe readily drawn off under siphoning-pressure that is augmented by the pressure from the nozzle 6, whereby the corrugating-rollsare kept hot and free from the water-load that would be carried therein ifno therefor was provided. I

The hollow rolls 3, 4 and 5 are mounted on bearings that have stuffing-boxes 9 and I are free to turn around the nozzles 6 and drain-tubes 8. 4

10 indicates a driving-pinion mounted on a shaft 11, the latter extending to any source of'power whereby the machine is driven.

12 indicates a spur-gear mounted on the outer end of the hub of the roll 3 and meshing with the driving-pinion 10. This spurgear 12 meshes with opposite side spur- -gears 13 and 14, in horizontal axial-alinement, and forms the real transmitter between them, the said spur-gears 13 and 14 being respectively mounted on the outer ends of the hubs of corrugated rolls 4 and 5 and whereby said rolls 4 and 5 are positively actuated without depending on the master or central shaper-roll 3 for drivingtransmission, it being the intention to drive the three rolls by means of the pinion 10 and said outer spur-gears 12, 13 and 14. Thus the rolls 3, 4 and 5 are simply corrugator shapers or crimpers that are adapted to receive and feed webs of paper between them for forming the corrugations in said webs. I A 15 and 16, respectively, represent hollow rolls or drums at the opposite ends ofthe machine, the drum 15 having its smooth periphery adjacent to but not touching the outer edges of the teeth of the'roll 4, and the smooth peripheral face of the drum 16 being mounted likewiseadjacent to but not touching the tips of the teeth of the roll 5, as best shown in Fig. 3. These drums 15 and-16 are provided with heat-medium in- 'lets 6, the, same as the'inlet 6 of the rolls3,

I 4- an' 5, such inlets for these drums being I ggcupledto the main steam conductor-pipe 7,

as shown; in Fig. 1 for their heatslipply.

IThe,,-' umS 15 and 16 are preferably mounted on inclinedbearings 17, their axes "tal--' alined-rolls; 3, 4 and 5, whereby said i .'driims' -can be adjusted by means of the *lscrewslS'So that theirperipheral faces can be brought.--'into jpropeiii-relation with the 4 tips of theiteeth of .theifolls-4'and5 to'suit sfiotwm of.

This endless-belt 21 travels in succession 'over transverse-idlers 22, 23, 24, 25 and 26 and in the direction of the arrows 27 that are placed closely thereto. The idler 23 is mounted in the uprights 28 and under control of the adjusting-screws 29 at each end thereof to exert the proper tension on the endless-belt 21 for the purpose hereinafter referred to. A similar endless-belt 21 is mounted at the opposite end of the machine on a successive series of idlers 22, 23, 24, 25 and 26, the succession being the reverse of that at the opposite end of the machine first described, and the arrows 27 adjacent the said belt also indicating its direction of movement, such direction of movement being the same as that of the endless-belt'first described, as best seen in Fig. 3.

30 indicates a transverse paste-roller whose periphery takes the adhesive from the vat 31 that is mounted diametrically be- .neath the r0114. The periphery of said paste-roller 30 lies closely to the circular path of the tips of the teeth of the corrugating-roll 4 so as to apply the paste to the now corrugated web of paper passing along the vat forward of said roll 4 to shortly meet with and adhere the backing strip or lining 32, thedatter feeding from a supplyroll 33, thence hlnder an idler 34 and thence in contact with the periphery of the heateddrum 15, the teeth of the roll 4 setting the corrugated strip of 'paper in contact with the simultaneously-passmg backing strip or lining and both now traveling forward in the direction of the arrow27 in close contact with the peripheral-surface of the said drum 15, whereby the paste is set and dried,

the endless-belt 21 serving to properly confine the corrugated-sheet with its backing or lining along the peripheral-surface of said drum 15 until idler .25 is reached when the now properly lined or backed corrugated sheet or web is diverted from said dru'm 15 to a windingrroll 35, the latter being'mounted transversely above the supplyroll 33 at one of the lower ends of the machine. a

36 indicates a Isupply-roll of paper that constitutes the web or continuous sheet leading into the machine between the corrugating-rolls 3 and 4, and passing over an idler 37 for proper supporting-direction. The

.web of paper passing over the roll 36 is the one used to form-the corrugated continuous s'heet orstripthat is finally wound on the thereto, as hereinbefore referred to.

paste-roller 40 is shown without any pastevat in connection therewith, but such pastevat can be conveniently mounted in juxta eonae roll 4, as best seen in Fig. 3. In order to stick the webs 36 and 38 together as they pass into the rolls 3 and 4, a paste-roller is used that applies the adhesive to the underside of the web 36, the two webs 36 and 38 being then properly stuck together while passing between said rolls 3 and 4 and'the web 36, which has now become corrugated,

taking its paste from the .roller'30 for the attachment of the backing or liningTiil e position and'duly supported on the frame of the machine. I have not shown the extra web of paper 38 nor the extra pasting deice 40 on Fig. 1, the latter simply showing a single web of paper that may be of greater or lesser thickness to suit the desired thickness of corrugated sheet.-

At the opposite end of the machine-another corrugated sheet is being formed from a lower supply-roll 41 of paper-webbing for the corrugated portion of the sheet, the webbing from roll 41 passing under an idler 42 and thence into the 'corrugator-jaws formed by the rolls 3.and 5, thence under a paste-roller 43 that applies the adhesive to the tips of the corrugations of the now corrugated sheet for attachment to" the backing-or lining formed by 'the paper-web '44, the latter feeding from aisupply-roll 45,

and thence over an idler 46 to the now the heated-drum 16 and the tipsofthe teeth stuck-together corrugated web and backing- Y passing between the peripheral-surface of of the heated corrugating-roll 5 whereby the said corrugated web and lining are set and properly stuck I for passing onward along the said peripheral-surface of the corrugated sheet is diverted from a hram, '16 to the transverse idler 26'andthence passes onward overthe-i dler 22mm windheated drum 16' into the space between the endless-belt 21 and said peripheralface. of the drum .16 .untilthe transverse idler 25 is reached, whence the now properly backed ing-drum' 47 swung from uprights 49 on the main-frame.

. In Fig. 1 a corrugated sheet, to the" right, is made of a single-thiclmess' webbing the same as that to theleft, but inFig. 3 l[ have b Suitable adjusting devices 54 are said till;

shown how the corrugated portion of the sheet can be made of two plies by utilizing an extra web 50 from a supply-roll 51, such extra web- 50 passing under an idler 52,

thence over a paste-roller 53, thence under .the idler 42 where its paste-covered face meets the inner face of the web from supplyroll 41,,and thence the now stuck-together webs 50 and 41 passing between the corrugating-rolls 3 and 5 for forming the corrugations therein, the double-thickness corrugated sheet thence passing beneath the paste-roller 43 and onward in the same I manner as that describedin connection with the single-web corrugated sheet hereinbefore described.

The paste-roller 53 is shown without a paste-vat, the same as that designated 40, s

but it is obvious that a suitable vat can be supplied and supported on the frame without showing just how herein.

vided in connection with each of the paper supply-rolls 33, 36, 41 and 45, as shown in Fig. 1,;for the purpose of exerting the proper tension on the paper while it passes intoand through the machine. Such tension 'devices can also be supplied in connection with the extra paper-rolls 38 and 51.

Adjusting-screws 29 are used in the uprolls 35 and 47, respectively.

I claim v 1.
